Designs
So now I know the dimensions I have to play with I can start to fiddle with ideas on what to make the box look like. In the following designs the black represents the carb mouth, the red the proposed box.
| 1 (cross section) | 2 (cross section) |
 |
 |
| This would cause restriction in the intake and pose problems for the amount of air available. Rams are needed. | Better in that the air is funneled in, but there is still a restriction and the “pipe” effect won’t help either. |
After looking at a few more ideas it is apparent what you need is air available from all angles and that a “pipe” in itself is not much use (unless gently curved) so the box needs to be made bigger and the rams can then be put in something like design 3:
| 3. (cross section) | 3.a (frontal) |
 |
 |
| A larger box with more air available and rams but is the space at the top large enough? | A frontal view showing dimensions of the box. This is replicated on the other side to cover both carbs. |
Rams are 10mm rings with 20mm in all directions before hitting the air-box wall. The top, due to restriction, only has 5mm. There is also a curvature to the top of the box to aid fitment.
In theory this would fit.
